The standard electrode potential \( (E^0) \) values of \( \text{Al}^{3+}/\text{Al}, \text{Ag}^+/\text{Ag}, \text{K}^+/\text{K} \) and \( \text{Cr}^{3+}/\text{Cr} \) are \( -1.66 \text{ V}, 0.80 \text{ V}, -2.93 \text{ V} \) and \( -0.74 \text{ V} \), respectively. The CORRECT decreasing order of reducing power of the metal is

1. A
   \( \text{Al} > \text{K} > \text{Ag} > \text{Cr} \)
2. B
   \( \text{Ag} > \text{Cr} > \text{Al} > \text{K} \)
3. C
   \( \text{K} > \text{Al} > \text{Cr} > \text{Ag} \)
4. D
   \( \text{K} > \text{Al} > \text{Ag} > \text{Cr} \)
